MediaQuery does not work with `screen` and `print` media queries

[techniq]

Describe the bug

Due to the inclusion of parenthesizes, new MediaQuery('screen') and new MediaQuery('print') do not work as expected.

Reproduction

REPL demonstrating window.matchMedia('...') compared to new MediaQuery('...').

System Info

svelte@5.30.1

Severity

blocking an upgrade

Ugh this is annoying but I don't think we can do much about it as changing the behavior would be a breaking change.

[paoloricciuti]

Maybe we could special case those words as there's a list of them 🤔

[paoloricciuti]

@techniq i think we can do it...in the meantime as a workaround you can do screen and (min-width: 0) to get the same behavior.

REPL

Can we keep this open and flag this issue for the next major version and just not add any parentheses at all?
(Alternatively I would recommend adding a new issue.)

[paoloricciuti]

Yeah let's create a new issue and we can it to the 6.0 milestone

@paoloricciuti thanks for the workaround and quick PR! I was thinking a keyword exclusion list would suffice (since it's small and known).
